Examined material.

Holotype ♂, China: Hunan Province, Badagongshan National Natural Reserve, Tianpingshan , 5.viii.2013, collected by Hu Li. Paratypes 1 ♂, same data as holotype, except 3.viii.2013 ; 1 ♀, Guizhou Province, Shiqian County, Fodingshan National Natural Reserve , 15.viii.1991, collected by Xiang-Sheng Chen.

Description.

Body color (Figs 1-3 ). Body background color black to dark brown. Head and face (Fig. 3 ) yellowish, with dark spots or stripes, frontoclypeus slightly milky white, eyes dark brown with reddish tinge, fading to gray; ocelli dark; apex of anteclypeus and gena black. Pronotum (Fig. 1 ) with anterior half dark brown, posterior half gray, striations on surface darker. Mesonotum (Fig. 1 ) evenly black with white tip. Forewing (Figs 1 , 2 ) brown, with several transparent patches at midlength and subapically; veins black with clear white spots. Legs yellowish with black or brown patches.

Body appearance (Figs 1-4 ). Head across eyes (Fig. 1 ) clearly narrower than pronotum; crown short with anterior and posterior margins almost parallel. Face (Fig. 3 ) as long as wide across eyes, surface with clear punctures and striations, central region slightly tumid frontally, distance between ocelli relatively large, approximately 8 × that from ocellus to adjacent eye. Pronotum (Figs 1 , 2 ) broad, 2.4 × wider than long, with strongly oblique striations. Mesonotum (Fig. 1 ) 1.5 × longer than pronotum. Forewing (Figs 1 , 2 , 4 ) with three subapical and four apical cells, venation prominent.

Male genitalia (Figs 5-11 ). Pygofer (Fig. 5 ) broad basally, lobe short and stout, caudal margin truncated, slightly depressed medially, ventral margin smoothly curved, with scattered marginal setae. Subgenital plate (Fig. 5 ) slender, of equal width throughout length, with relatively long hair-like setae, its length as long as ventral margin of pygofer. Dorsal connective (Fig. 6 ) strongly developed, S-shaped, with long slender process produced on ventral margin directed caudad and twisted. Style (Fig. 7 ) with apophysis stout, angled dorsally at basal 1/3, gradually tapering to pointed apex, with few marginal setae. Connective as in Figs 8 , 9 . Aedeagus (Figs 10 , 11 ) with basal apodeme and shaft short, the latter shorter than 1/2 length of whole aedeagus, tapered in lateral view to truncate apex, bent dorsally.

Measurement.

Body length (including tegmen): 4.3 mm.

Distribution.

China (Hunan and Guizhou provinces).

Etymology.

The specific epithet of the new species is derived from the Latin words albus (white) and picta (spot), referring to the white tip of the mesonotum and white spots on the forewing veins.

Remarks.

This species can be readily separated from other congeners by the contrasting color pattern of its mesonotum, white spotted forewing veins, and different shape of the aedeagus and dorsal connective.
